Methods of measurement for radio transmitters - Part 11: Transposers for FM sound broadcasting

Applies to transposers operating in accordance with CCIR Recommendation 450 for FM sound broadcasting at VHF, including stereophony. Also covers requirements for other multiplexed subcarrier services. Lays down detailed methods of measurements, selected and recommended for assessing the essential performance and general characteristics of FM sound broadcasting transposers.

Meßverfahren für Funksender - Teil 11: Umsetzer für FM-Tonrundfunk

Méthodes de mesure applicables aux émetteurs radioélectriques - Partie 11: Réémetteurs pour la radiodiffusion sonore à modulation de fréquence

Concerne les réémetteurs destinés à la radiodiffusion sonore en VHF à modulation de fréquence, y compris en stéréophonie, conformément à la Recommandation 450 du CCIR. Couvre également les besoins d'autres services à sous-porteuse multiplexée. Décrit en détail les méthodes de mesure choisies et recommandées pour évaluer les principales caractéristiques générales et la qualité de fonctionnement des réémetteurs de radiodiffusion sonore à modulation de fréquence.
